Scientific paper

PSR J0108-1431 is a 170 Myr old, very faint radio pulsar at a distance of 240 pc, among the nearest neutron stars to Earth. Thanks to its proximity, PSR J0108-1431 offers a unique opportunity to study X-ray emission from a very old, almost dead pulsar. A short Chandra observation has shown that it is much brighter in X-rays than one could expect for such an old pulsar with a very low spindown power. However, the number of detected counts was too small to definitively characterize its spectrum, and the time resolution too low to detect pulsations. The proposed study of the X-ray spectrum and pulsations of PSR J0108-1431 will provide first definitive results on the X-ray properties of very old pulsars and test the pulsar evolution models.
